Thanks for the information -- I got scared by "SysV init". This actually
does look very nice.

The OpenRC is sysvinit compatible, but it has few of sysvinit's flaws.
It has named runlevels, the presence of an init script does not cause it
to start and it is in my opinion a joy to use.
I suggest that you try OpenRC before drawing conclusions. You can
install Gentoo FreeBSD in a jail. There are instructions for this on the
Gentoo wiki:
http://wiki.gentoo.org/wiki/Gentoo_FreeBSD#Howto_run_G.2FFBSD_in_vanilla_FreeBSD.27s_jail
If you find deficiencies, I am certain that the OpenRC developers would
appreciate feedback regarding them.

Greetings,
I was just wondering what it is that FreeBSD does that makes it take so long
to boot. Booting into Ubuntu minimal or my own custom Linux distro,
literally takes 0.5-2 seconds to boot up to shell, where FreeBSD takes about
10-20 seconds. I'm not sure if anything could be parallelized in the boot
process, but Linux somehow manages to do it. The Ubuntu install I do pretty
much consists of a shell and developers tools, but it still has a generic
kernel. There must be some sort of polling done in the FreeBSD boot process
that could be parallelized or eliminated.
Anyone have any suggestions?
Note: This isn't really an issue, moreso a curiosity.
The single process nature of rc is a big part of the problem, as
is the single AP bootup of FreeBSD right before multiuser mode. There
are a number of threads that discuss this (look for parallel rc bootup
or something like that in the current, hacker, and rc archives -- the
most recent discussion was probably 6~9 months ago).
Given past experience, a big part of getting past the parallelized
rc mess would be to make services fail/wait gracefully for all their
resources to come up before proceeding. It's not easy, but it's
possible with enough resources.
HTH,

Gentoo FreeBSD shares OpenRC with Gentoo Linux. OpenRC is a BSD 2-clause
licensed System V init system replacement that supports parallel boot.
Its boot performance is competitive with systemd and Ubuntu's upstart.
If FreeBSD's init system is serializing the boot process, it might be
worthwhile to consider importing OpenRC.

Please don't change any of the user-facing aspects of the RC system. One
of the things that brought me (and many others I know) to FreeBSD,
besides working sound, was having an rc.conf that was easy to configure
instead of the nightmare that is System V init.
